About the Astronomia family
The Astronomia, first shown in 2014, is the watch that established Jacob & Co. in high watchmaking. Its movement is built vertically inside a domed sapphire case, with rotating arms that carry the time display, a multi-axis tourbillon, a small globe and a faceted moon, all turning around the centre of the dial.
The catalog includes Astronomia references in gold and titanium, some set with diamonds, with variations such as the Astronomia Tourbillon and themed editions. These are low-volume pieces, so full documentation, the original box and a service history from Jacob & Co. are essential.
